Comparison of three kinds of different number of side holes of the drainage tube drainage effect

Objective To investigate the effect of different number of side hole chest tube in the closed thoracic drainage of drainage.Methods A total of 360 patients were divided into three groups: group A with unilateral drainage holes;group B with bilateral drainage holes;C group with three side holes of the drainage tube;observed of drainage,drainage,drainage,drainage tube obstruction traits,drainage pipe jacking lung,drainage tube side hole was exposed or side hole off to the chest wall,or encapsulated liquid pneumothorax after operation.Results The drainage volume of three groups of patients with tube and drainage time comparison with no significant difference(P 0.05).Unilateral hole group was 22.5%,bilateral hole group was 10.0%,three side hole group 20.0%.The occurrence of A group and B group complications rate between B group and C group,the complication rate were significantly different(PA-B0.05,PB-C0.05).Conclusion Closed thoracic drainage of bilateral drainage holes less complications conclusion after opera tion,and is suitable for the closed thoracic drainage.but patients with pneumothorax lock line second intercostal tube hole arranged unilateral chest tube is better,can reduce the pressure on the top of the lungs,side hole is exposed to the chest wall or removal of complications such as.
